Transcript for Instant Index: Pope Benedict on His Decision to Step Down and Pursue a Life of Prayer

Our "instant index" tonight starts with pope ben ticket speaking out and saying it was god who told him to step down as pope and break the 600 year tradition. He says he did not hear god's voice or have visions with angels but experienced what he calls a mystical experience in which god's plan was revealed to him that he should dedicate the rest of his life to prayer. Look at this, what are two little girls 9 years old doing on the wing of planes? Rose powell and brewer are cousins and professional dare devils. Watch them strike poses 0 top these planes while going 100 miles per hour. Today they became the youngest sink niezed wing walkers in the world. The girls do admit they were scared but say it felt a little like being on a roll eh coaster or soaring like a bird. We thank all of you for letting us look at the sky with you last night, the rare blue moon right there over mount hood and next to the washington monument and there was the moon pink at a baseball game in missouri and in california, the silhouette of a plane. We loved your pictures, this one from arizona and the fantastic golden moon in new jersey early in the morning. Right there, a truly blue moon in north carolina. By the way, it appears blue when there is ash in the air. Again, thanks.
